What id prejudice? Where in the world have you seen prejudice? What are the effects of prejudice?

Prejudice is an unreasonable dislike of a particular group of people or things, or a perference for a one group of people or things over another (elec. dictionary). By verb, it is influencing them so that they are unfair in some way. I think everywhere we go, there might be prejudice, because people can dislike and many people will dislike something if they don't like things. Even we dislike many things, I dislike that our school is a container box. The effect of prejudice can make others really feel bad. If you keep that dislike in and not shout out but if someone shout out then that person can hurt others also that person might be called carzy person.
